- Patented Mar. *7, 1916,

Application filed April 14, 1910, Serial No. 555,347. Renewed July 23,1915. Serial No. 41,580.

August 4, 1908. In this system, the work-' ingmans wages areautomatically calculated and indicated. A rate keyboard and a timekeyboard are provided, the time keyboard being automatically operated bytime mechanism to set up a time element in the master machine providedin the system, and the rate keyboard being automatically operated uponactuation of the workingmans number keyboard to set up the rate elementin themultiplying mechanism, and this multiplying mechanism combines theelements into the wage element and transfers thewage element to thetransposing mechanism, which in turn sets up the wage element on thewage keyboard, which wage keyboard in turn controls the indication ofthe wage element. In the multiplying mechanism in the main system ofsaid co-pending application, however, rate elements of only a few fixedamounts could be set up, thus limiting the range of the system. Amodified arrangement is shown in said application, in which severalmultiplying mechanisms are connected in tandem, each receiving a factorof the rate element, the several multiplying mechanisms seriallymultiplying together the factors to produce-the complete rate element.

"This modification, however, involves complicated mechanism, andbesides, involves considerable time in its operation.

One of the main features of my invention in the present application isto provide multiplying mechanism by means of which'rate form of improvedregister mechanism, which I have disclosed in my co-pending application,Serial No. 443,802, filed July 16, 1908. The feature of this registermechanism is that the positive operation of the" order members and theiroperation through the carry-over mechanism can be simultaneous andconcurrent. By .associating a register of this kind with the improvedmultiplying mechanism which will accommodate numbers of inore than oneorder digit, greater speed of operation can be accomplished. The timeelement is set up either automatically or manually on the mastermachine, and the rate' element is set up on the multiplying mechanismeither automatically or manually. The multiplying mechanism comprises aplurality of multiplying sets corresponding to a number of decimalorders. This itself will save much time, and the order digits of therate element instead of being set up in a certainnecessary order, can beset up either separately or simultaneously, or in any order orcombination. Connected with each mul tiplying set is a transmissiongear, eacn gear being connected in driving relation with an orderdriving pinion, which pinions are adapted for connection with thedriving gears of the receiving register mechanism. These pinions arealso controlled by the master machine and are moved together step bystep to be carried into successive engagement with the register drivinggears in a manner which can be more fully explained later. The drivinggears for the multiplying mechanism are also driven by the mastermachine. The operation of the master machine is clearly illustrated inco-pending application Serial No. 333,660, filed September 7, 1906,there being two driving shafts operating alternately, the one shaft forcontrolling the selection of the orders and the other shaft forcontrolling the insertion of entry in the selected order. The functionof the. master machine in my present invention is the same, the machinebeing connected with shafts mounting the pinions to cause longitudinalmovement of said shafts to carry the pinions successively from one setof order drive wheels to the next set of order drive wheels of theregister, the machine being connected with the drive gears of themultiplying mechanisms tosimultaneously rotate said gears after eachlongitudinal adwhich is substantially like that described in" mycopending application Serial No. 443,802

referred to, A1 and A2 represent side walls of suitable supportingframework, each side wall terminating at the front end in a bear ing hubA3 and at therear end in a bearing hub A24. Pinned in the front hubs A3is a shaft A5, and supported in the rear hubs A4 is a shaft A6. On theshaft A5 the order indicating sets A7 A7 A7 ,v and so on, are molinted.Each set has a spur gear A8, a carrying gear A9 and a numeral wheel A10,each numeral wheel having ten, The members of each order set'are'j.secured together and rotatably mounted on shaft A5. On the shaft A6 setsof driving di gits.

and carry-over mechanism are mounted, each comprising difierential gearsA25 and A26, a drive gear A27,.a differential pinion A28 carried by thedrive gear, a transmission gear A29, a carry-over gear A30 and a bevelgear A31, the sets following the units order set also having a bevelgear A32. Suitably mounted in bearings A33 extending from the frameworkare the transmission pinions A34, each connectingthe bevel gear A31 ofone carry-over-driving set to the bevel gear A32 of the adjacent set.

-There can, of course, be any number of order sets and driving andcarry-over sets.

The bevel gear A25 of the units carry-over driving set is'rigidlysecured to the shaft A6, all'the other members of the sets beingrotatable thereon. With the register mechanism thus far described,positive actuation of the order sets upon turning of the driving gearsA27 and actuation of the order sets through the operation of the carryover mechanism, can take place concurrently and simultaneously, as hasbeen shown in the copending application Serial No. 443,802 referred to.a

A38, A38 and A38 represent shafts, the shaft A38 telescoping over theshaft A38, the shaft. A38 telescoping in turn over the shaft A38". Threebearings, A39, A39 and A39, support these shafts, the bearing A39directly receiving the shaft A38, the bearing A39 directly receiving theshaft A38, and the bearing A39 directly receiving the shaft A38. Theshaft A38 has the keyway A40, the shaft A38 has the keyway A40", and theshaft A38 has the keyway A40. Secured to the left end of the shaft A38is the transmission pinion A41; at the left end, of-shaft A38 is securedthe transmission pinion, A41"; and at the left end of shaft A38 issecured the transmission pinion A41, the spacing between these pinionscorresponding to the spacing between the register driving gears A27. Theshafts are not longitudinally movable with respect to each other. Theshaft A38 is confined on shaft A38 between the collars A42 and A43,

- and the-"shaft A38 is confined on shaft A38 between the collars A44and A45 on said shaft. Ordinarily, the collars A43 and A45 rest againstthe left faces of the bearings A39 and A39, respectively, and thetransmission pinions' A41 -and A41 are in mesh with the units and tensgears A27 of the register mechanism,'the pinion A41 being disconnectedfrom the register and at the'right thereof. Longitudinal movement of theshaft A40 to the left will be transmitted to collar A43 of shaft A40 andfrom the collar A45 at the left end of said shaft A40 to the shaft A40,and return longitudinal {movement of the shaft A40 to the right istransmitted through collar A42 to the shaft A38 and through the collarA44 to the shaft A38 longitudinally together, but may rotate relatively.The means for longitudinally moving the shafts is shown at the right ofFig. 1. The head A46 at the right end of the inner shaft A40 is held ina bearing sleeve A47, which is secured to the left end of the screwshaft A48, which screw shaft passes through the bearing A49, the screwshaft having a keyway A50 forreceiving a key extending from saidhearing, so that rotation of the screw shaft in said bearing isprevented. A gear A51 has screw-threaded engagement with the screw shaftA48 and extends into slot A53 cut in the bearing A49. Rotation of saidgear will result in longitudinal movement of the screw shaft and of Theshafts must thus move...

the shaft A40 connected therewith. The

gear A51 meshes with gear A54, which connects with the shaft M66 of themaster machine Mm, said machine being here represented onlydiagrammatically, but described in full detail in co-pending applicationSerial No. 333,660 referred to.

Paralleling the telescoping shafts a looking bar A55 is mounted insuitable guide-- ways A56. This bar has the locking web A57 for engagingthe teeth of the register driving gears A27 to lock said gears againstrotation. The web, however, has the unlocking notches'A58 equal innumber to the transmission pinions A41, and disposed in the same planewith said pinions, so that when said pinions are in mesh with a set ofthe driving gears, the teeth of said driving driving gears, however,being in looking engagement with the locking web and thus prevented fromrotation. The bar A55 is moved with the transmission pinion shafts,being connected with the inner shaft A by means of an arm A59 extendingfrom the bar and engaging at its end in the slot A60 formed in thebearing sleeve A47.

Longitudinal movement, therefore, of the.

446,895 already referred to, and" it is not thought necessary to hereshow all these details. As shown in said co-pending application, thegea'rs E4 are driven in accordance with the set-up in the mastermachine, while the shafts E49 connect through suitable gearing with theselector shaft E25 of the multiplying mechanisms, as shown in thecopending application, so that after a set-up of the electro-magnetsE37, rotation of the shafts E49 will cause the proper multiplying gearsets to be connected in for service. In the co-pending application, themultiplying gear sets of the units order are shown 7 as normally inmesh. Instead of this construction, I use in the present application anadditional gear E11 which normally has its teeth in engagement with theteethon the locking member E8 The operation, however, is the same asthat in said co-pending application, namely, that upon energization ofone electromagnet and rotation of the corresponding shaft E49, the gearsof the corresponding multiplying set are brought into mesh and at thesame time the universal bar E55 is moved to withdraw the gear E11 fromlocking engagement with the block E8 so that upon rotation of thecorresponding driving gear E4, the gears of the connected in multiplyingset may rotate: 'Each multiplying mechanism set has also multiplyinggear sets ranging from 0 to 9; that is, in each set the multiplyingrange is from 0 to 9. The shafts E12i of the multiplying mechanism sets,terminate in pinions 17- and these pinions mesh with the transmissiongears E19 The transmission gear E19 is pivoted onthe tubular shaft E38,and has a key for engaging in the keyway 1340?, the gear being con--fined against sidewise movement in the slot A61 in the bearing A39. Thetransmission gear E19 is pivoted on the tubular shaft A38", and has akey engaging in the keyway A40 said gear being confined in slot A61 inbearing A39. The transmission gear E19 is pivoted on the inner shaftA38, and has a key engaging in slot A40. Each shaft can, therefore,slide through the transmission gear mounted thereon, and will be rotatedupon rotation of the gear.

After the above description of the various parts and mechanisms, theoperation will be clear. Take, for example, in a time-keeping account,the multiplication of time and rate elements to. obtain wage elements.Suppose that the time element-is 56 hours, and the rate element 27 perhour. If the apparatus shown were associated with the automatic systemof my co-pending application, Serial No. 446,895, the-number of theworkmen to be credited with the wages would be set up on one of thekeyboards, which would result automatically in the operation of the ratekeyboard to set up the rate element on the multiplying mechanism, andoperation I of the time keyboard to set up the time eleument in themaster machine, and the "master machine then operating the multiplyingmechanism, the rate and time elements would be combined and set up asthe wage element on the register mechanism through the transmissiongears and pinions. Instead of having the rate and time elements set upautomatically upon set-up of the workmans number, the rate and timekeyboards could be directly actuated manually. The rate element in theexampl is 27, and therefore the 7s digit electromagnet of the unitsmultiplying mechanism set E will be energized, and in the tens ordermultiplying mechanism set E the 2s digit electromagnet will beenergized. In the master machine, the number 56 will be set up in themanner which has already been carefully described in co-pendingapplications, the master machine operating first to carry the drivingmechanism into the field of the units order, then causing operation ofthe driving mechanism to rotate the shaft M66 in proportion to thenumber set up'in the units order; the driving mechanism being thencarried into the field of.

the tens order and again operated to be rotated in proportion to theunits set-up, and so on, throughout the range of master ma chine orders.The shaft M66 of the master machine controls the movement of the drivingmechanism into the various order fields, and the shaft M122 controls thetransmission of the order set-up to external mechanism. In thearrangement shown in the present application, the shaft M66 connectswith the screw shift shaft A48 and With the set-up mechanism of themultiplying mechmachine now starts, the shaft M66 is first rotated tomove the screw shaft and the rod A55 to the left one order, to carry thetrans mission pinions A41 into mesh respectively with the units, tensand hundreds register mechanism driving wheels A27, the unlockingnotches in the locking bar A57 being then arranged so that these driveWheels are free to rotate. Simultaneously with this movement of thetransmission pin- 10I1S, the gearing E49 is driven, and .the cam wheelsE45 -of the multiplying mecha-' nisms rotated to operate the clutchmechanlsm to connect in the 7s digit'multiplying set gears in the unitsorder mul tlplying mechanism and to connect in the 2s digit multiplyingset gears in the tens multiplying mechanism. After this set-up in themultiplyingmechanism sets has been completed the shaft M66 nism'of themaster machine is brought into I the field of the units order, in whichthe number 6 is set up, and therefore, whenthe shaft M122 is rotated, itis given .6 revolutions, and the driving gears E4 are simultaneouslygiven .6 revolutions. Theg'earin'g relations between the gears E4 andthe pinions E5 is 1 to 10,

and therefore pinions E5 and the shafts E6 on which they are mounted,will be rotated 6 revolutions. order'multiplying mechanism set, the 7 sdigit multiplying gears are in mesh, and

therefore the six revolutions of the units shaft E6 will be transformedinto 42 revolutions of the .units shaft E12? The gearing relationbetween the pinions E17 and the transmission gears E19 respectively, is10 to 1. The 42 revolutions of theunits shaft E12 will resultin 4.2revolutions of the gear 1519 shaft 'A38 and'the transmission pinion A41The gearing relation betweenthe transmission pinions A41 and theregister drive gears A27, is 2 to 1, on account of the differentialmechanism. When the'units transmission pinion, therefore, makes 4.2revolutions. the amount 42 is carried thereby into the register;However, at the same time that this entry is made, an entry is madesimultane- A41 connected with the tens multiplying In the units be 3.5revolutions of this gear.

' mechanism set.. The shaft M122 rotating .6

of a revolution, causes 6 revolutions of shaft E6 of the tensmultiplying mechanism set and the 2s digit multiplying train being setfor operation, the 6 revolutions are trans- 70 formed into 12revolutions of the shaft E12-2,

which results in 1.2 revolutions of the shaft A38 and of the pinionA41".

' be added to the 4 and 6 will be the indication in the tens order,while the hundreds order will indicate 1, having been moved to thisposition by the carry-over mechanism when 1.2 revolution was made in thetens order, and the total indicationwill be 162, which is 'the result ofthe multiplication of 27 by 6.

After this concurrent entry in the register,

the-shaft M122 stops and the screw shaft A48 is advanced anotherorder'to carry the transmission pinions A4l into mesh respectively withthe tens, hundreds and thousands register drivin g gears, the looking.shaft A55 being likewise shifted to unlock said driving wheels and tore-lock the units drive wheel. The master machine.

driving mechanism is also brought into the field of the tensorder, inwhich 5 has been set up. The multiplying mechanism, however, retains itsset up of 27. Shaft M122 is now given .5 revolutions, and the drivewheels E4 are simultaneously given .5 revolutions. On account of thegearing relations and the set-up of the 7 s digit in the unitsmultiplying mechanism set E, the shaft A38 will be given 3.5revolutions, and' the transmission pinions having been advanced anorder, this 3.5 revolutions will be transmitted'from the pinion A41* tothe tens order register driving wheel, and there will The 2s digit beingset/ up in the'tens multiplying mechanism set E the shaft A38 will begiven 1 revolution, and the pinion A41 being in mesh with the hundredsorders register driving wheel, thiswheel will. be given 1 revolution. Wetherefore have had a simultaneous actuation in the register of 3.5revolutions through the tens wheel and 1 revolution through the hundredsdriving wheel. As a result of the previous entry when 6 was themultiplicand, the tens wheel indicated 6, and the 3,5 revolutionsthrough the tens wheel will cause the addition of 5 units to the tenswheel and cause a carry-over operation into thehundredsorder and leavethe indication on the tens order, 1. .In the hundreds order, after thefirst entry the indica tion is 1. The entry ofthe 3.5 revolutions Ithrough the tens order added 3 units to the unit and the indication inthe thousands or der made 1. We therefore now have the.

final indication of 1512 on the register,

which is the result of the multiplication of" There being no set-ups inthe master machinebeyond the tens order, the rotation of the shaft M66will be reversed, as has been described inco-pe'nding application SerialNo...333,660, and screw shaft.A48 will be drawn to the right to itsordinary position, with the transmission ,pinions A41 and A41 in meshrespectively with the units and tens register driving gears. Thetransmission mechanism E49 will also receive reversed rotation, and theclutch mechanisms in the multiplying mechanisms will be re leased andthe multiplying set'gears restored I to their normal position, as shownin the drawing.

It will thus be seen that after the parts driven by the master machineshaft M66 have been properly set with reference to one order, and themachine shaft M122 started, all the steps of the multiplying cycle willbe concurrent and simultaneous. The multiplying operation, the positiveentry of the result and the operation of the register carry-overmechanism will all be simultaneously and concurrently performed, andupon the completion of rotation of shaft M122, allthe steps will havebeen completed and the result of the cycle indicated. No matter how manydigits have been set up in the multiplying mechanism, all the orders ofthe set-up number will be multiplied simultaneously by any order set upin the master machine and concurrently with each of such multiplicationsthe result of the multiplication will be carried into the-register andindicated. It is very evident that a considerable saving of time iseffected :by this automatic arrangement. The time consumed in carryingthrough a multiplying operation will be the same, no matter how manydigits the rate element involves.

As shown, each indicating order set, of the register includes acommutator A62 having 10 segments adapted to be engaged .by brushes A68to control circuits of indicating or other apparatus. In the systemshown in my co-pending application, Serial No. 446,895, these circuitsinclude the wage keyboard setting up electromagnets.
